Data Acquisition

[Jeff]

Brian, I'm not suggesting you give anything away.  I'm saying that once someone gets your product and can step up to comment on it, the rest of the forum will get a better look inside it.

Anyway, I think we're on the same page...  If someone truly wants a data acquisition system, they should be contacting manufacturers & distributors for info...  The BBS is simply a means of finding out who (if anyone) uses what...

[BRG]

Jeff, Yes we are on the same page.

Now all you fast guys stop picking on me!!!!!!!!!!

I think it's all a waste of time and money.  LOL   ;)

I know a guy who works at Dunkin Donuts that took a GPS system out of his parents car, and duct taped it to his tail section. He said his system can do way more than all of yours.

That's all fine and good but he's got nothing on my man from the Kwiki Mart.  ::)

GPS isn't accurate enough to use for this type of datalogging.  

[BRG]

ya, GPS is worthless!!!

[cornercamping]

I wouldn't say all that.  But it is worthless in "motorcycle" type applications unless you are trying to find out who stole your bike. For this specific application, GPS doesn't do what people think it does.  Embedded applications like this don't have the software to correct errors imposed by using GPS.  Not possible. That's why "Navigation Systems" in cars use DVD and a couple here and there use HD's.  The Geocoding is stored on a DVD or other source.  That type of memory isn't available in an application like this, therefore, the accuracy is only based on raw NEMA data with no correction.

Phew.... ;D

Dude - you have a very limited knowledge on this subject and it's obvious.  You may know the basics, but don't pretend for a second that you're an expert.  And certainly don't go bashing this product before you know anything about it.  Take it from someone with a 4-year degree in GIS & GPS applications and programming...it's very possible this equipment is accurate enough to give valuable information.  Down to the millemeter, no.  Down to the meter or sub-meter on a good day, yes.  That should be good enough for these purposes.  If companies like AT&T, SBC, Quest, and Ameritech trusted me to be their GPS guru - I think you should take my word for it too.  It's also possible Baker's stuff is crap - but until we know more I say we give him the benefit of the doubt...don't you?

well someone better tell Aimsports as their new data logger uses it  ;)

[BRG]

10bomb knows what he is talking about.

Again like I said others think they do and the customer looses out.

We should just trash the whole thing, Ha.

Actually, I did speak with AIM.  They use an 8 Channel Trimble GPS chipset that utilizes the TIPS format for decoding.  Therefore, without necessary error correction software, I highly doubt it will get sub-meter.  Plus, the time to first fix and the almanac provisioning has been issues for them. I've done research on all of this regarding AIM devices for a customer of ours. Furthermore, I'd like to know who's providing the geocode for the race tracks. Now, I'm not saying that using other things along with GPS won't help, such as Gyro's, accelerometers, ect. wouldn't help, but still.  Accurate, nope not really for this application.  As far as my backround in GPS, it's more than likely not as advanced as yours is, and I have no problem admitting that, but Scott Dow, our Director of GIS is.  He is on our board of directors, and also is a partner in this company:  www.aerotecusa.com/

Not trying to start a pissing match. It's just interesting discussion for me.

Define: "on a good day."

Does that mean all satellites visible, all satellites being tracked, and no radiated emissions interfering with the functioning of the hardware?

Hmm.. from an electronics stand point, being that I have a BSEE, I can think of a TON of electrical issues that could possibly come into play on these units, but I'm not going to go there yet.  ;)

Like I said, not looking to argue, just interesting discussion.   8)
